The ADS1158 is a flexible, 16-bit, low-noise ADC optimized for fast multi-channel, high-resolution measurement systems. The ADS1115 is a 16-bit precision analog-to-digital converter (ADC) with an I2C interface. In this guide, we shall cover: Interrupt vs DMA. Whether you're working with synchronized signals or need parallel data streams, Red Pitaya’s ADC can handle the most complex tasks with ease. 16 Channel 16 bit Analog to Digital Converters - ADC are available at Mouser Electronics. Those can be valid for simple application like temperature control of a room or heat-sink. I don't claim to be a linux device driver or alsa expert, so I'd love to get some knowledgeable feedback about how to structure things. The AD7291-EP is a 12-bit, low power, 8-channel, successive approximation analog-to-digital converter (ADC) with an internal temperature sensor. Multiplexers (muxes) and switches fan the input I²C/ SMBus signals to two, four or eight downstream channels of SCx/SDx pairs. Description The ADC to I2C subsystem example demonstrates how to use the internal ADC to convert an analog signal into a digital representation and transfer the result through I2C. 18-Bit, Multi-Channel ΔΣ Analog-to-Digital Converter with I2C™ Interface and On-Board Reference I2C 18 bit Analog to Digital Converters - ADC are available at Mouser Electronics. Analog Devices offers a comprehensive portfolio of switches and multiplexers covering single to multiple switch elements with various signal ranges in a variety of packages to best suit customer application needs. Each part operates from single 2. It is widely used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication. The I2CAD8 is a single-supply low-power 12-bit data acquisition device that features a serial I2C interface and an 8-channel multiplexer.
